At one point, I realized this was an opportunity to show my emotions. So Jokingly I squeezed her sides."Aah, stop it! hahaha" She said as she started ...giggling. I started to somewhat wrestle with her and at one point, I ended up in the corner on the steps with her in my lap. She was still laughing and hadn't really been bothered by it. I immediately started to get a raging hard-on."Looks like someone's enjoying themselves" she said as my prick pushed into her ass cheek."Sorry, I didn't.. I. Her sexual arousal had become so intense it was getting harder keeping her happy in the bedroom. Then suddenly disaster struck. I had been working outside one day in the yard when I suddenly hurt my back. I was told not to do anything physical for the next few months. My wife and I were devastated, as I no longer could perform in the bedroom. My wife needed sex more than ever as her levels of arousal soared to new heights. I knew I couldn’t keep her at bay for very long and I needed to come up. When I got down to the dressing room, I asked. "You need some time alone?" No, I seem to be over my little affliction." he said."Okay then tell me why you walked to the office to tell Joan about the gang rather than call on the radio?" I asked."If somebody takes down one of the office staff, he could steal a radio. If that happened he will know exactly where and how to pick us off. The less we use the radio the better." he said."Point taken," I replied."Lesson learned in the sand box," he. Next he went to a lingerie boutique where he was waited on by a mature saleswoman who was only too pleased to help him choose a selection of lingerie 'for his wife's birthday'. She made no comment to the fact that Mike new the exact sizes of the items he wanted; he was simply a thoughtful husband who new his wife's clothing size.He took his purchases back to the car and braced himself for the next series of acquisitions. So far it had been easy to explain any of the purchases to an enquiring.
